Waiting for Elisabeth Moss on the rooftop of Hollywood's Sunset Tower Hotel, it's impossible not to conjure her Mad Men character, Peggy Olson: the mousy hair, the dowdy dresses, the prickly bookishness.

But the rockabilly black boots that appear on the poolside terrace belong to an entirely different creature-a thoroughly modern Moss. Sporting cut-off jeans and a tantalizing black tank, with a fedora crowning her chin-length hair, the 29-year-old vibrates with sexy confidence.

Where's the pasty skin of the frequently maligned 1960s ad copywriter she plays on TV? Or the sealed lips of the prim star who won't say a word about her love life, let alone her whirlwind 11-month marriage to Saturday Night Live's Fred Armisen?

Not on this rooftop.

This glowing, dewy-faced woman is eager to open up. She's cheery, funny and sincere-any girl would long to be her BFF (and ask if she's down for trading outfits). Moss pops some gum and a big grin, folds a stylish pair of gold shades into her low-cut top and dives into gabbing.

First order of business: the startlingly voluptuous photo spread she just shot for Page Six Magazine.

"People will be surprised," she laughs. "I don't walk around in a Burberry trench coat and bra all the time, but it's fun to embrace that part of yourself. I think every woman has a sexy, adventurous side."

Moss, who is off to New Zealand to star as a detective in the new Sundance Channel's miniseries Top of the Lake, confesses she's feeling a bit seductive these days.

"Sometimes you just wanna wear somethin' real tight and show it all off," she says, blue eyes twinkling. "Lately I've been in that mood."

Any reason she's feeling so...revealing?
